Description

Technical Field

[0001] This disclosure relates to the field of thermoacoustic instability technology, and more particularly to a heat source device for Rijke tubes and a method of using it. Background Technology

[0002] Combustion instability results from the full coupling of unsteady heat release and sound waves in the combustion system. The well-known Rayleigh criterion states that when unsteady heat release and sound waves are in phase within the combustion system, heat energy is converted into sound energy. Within a finite time, the sound energy within the system increases rapidly. If the increase in sound energy due to thermoacoustic coupling exceeds the dissipation of sound within the system, combustion instability will occur. Conversely, when unsteady heat release and sound waves are out of phase, sound energy is converted into heat energy, and combustion instability is suppressed. The Rijke tube, used to study thermoacoustic oscillations, is typically a vertically placed, open-ended hollow tube containing a heating element. When the heating element is fixed to the lower half of the tube, the tube's resonant frequency is excited, producing a resonant sound.

[0003] In the thermoacoustic experiments of Rijke tubes, selecting a suitable heat source is a key factor in achieving oscillation phenomena and expanding the control range of heating parameters. Therefore, during the design of the heat source section, it is necessary to select a heating element of appropriate length that can withstand the required power without melting, while keeping the inner diameter of the heat source section fixed. This element must be rationally arranged and fixed within the heat source section to ensure that it neither short-circuits itself nor contacts the inner wall of the metal heat source section. However, current Rijke tube experimental research typically uses heating elements with a single heating wire or a spring-shaped heating wire. This involves winding the single heating wire or spring-shaped heating wire onto a cross-shaped or U-shaped insulating sheet, which is then fixed inside the tube for heating. However, this heating method often suffers from insufficient space within the tube, overly compact arrangement, and unstable fixation, easily leading to short circuits or contact with the tube wall. Furthermore, wiring is difficult, and the insulating sheet is prone to charring and deformation under prolonged high-temperature conditions.

[0004] Therefore, how to solve the problem of insufficient space for heating elements to be arranged inside the tube, overly compact arrangement and unstable fixing in the existing technology, which leads to short circuits or contact with the tube wall of the heating elements, is one of the important problems that urgently need to be solved in this field. Summary of the Invention

[0005] In view of this, the present disclosure provides a heat source device and method for using Rijke tubes to solve the problems of insufficient space for heating elements to be arranged inside the tube, overly compact arrangement, and unstable fixing, which can lead to short circuits or contact with the tube wall of the heating elements themselves.

[0006] According to one aspect of this disclosure, a heat source device for a Rijke tube is provided, comprising: a heating support, a first insulating member, a connector, a heating element, and a second insulating member. The connector has a first groove for placing the heating support and a second groove for placing the first insulating member. The heating support is located in the first groove and is used to fix the heating element, which is evenly distributed on the heating support. The first insulating member is located in the second groove and is used to isolate the contact between the charged heating element and the Rijke tube. A first through hole for placing the second insulating member is also provided on the side wall of the connector, and a second through hole for placing the second insulating member is provided on the side wall of the first insulating member. The first through hole and the second through hole communicate with each other, and the second insulating member is inserted sequentially along the first through hole and the second through hole until it contacts the inner side wall of the first insulating member.

[0007] According to one aspect of this disclosure, the heat source device for a Rijke tube has a circular heating support.

[0008] According to one aspect of this disclosure, a heat source device for a Rijke tube has a plurality of third through holes and a fourth through hole on the heating support, with each third through hole being evenly distributed along the circumferential direction of the fourth through hole.

[0009] According to one aspect of this disclosure, a heat source device for a Rijke tube has a plurality of first bosses on the outer side wall of the heating support and a plurality of third grooves on the connector, each first boss being adapted to each third groove.

[0010] According to one aspect of this disclosure, in a heat source device for a Rijke tube, the radial dimension of the first groove is greater than the radial dimension of the second groove.

[0011] According to one aspect of this disclosure, in a heat source device for a Rijke tube, both the first insulating element and the connecting element are hollow structures.

[0012] According to one aspect of this disclosure, in a heat source device for a Rijke tube, the radius of the pitch circle formed by each third through hole is smaller than the radius of the Rijke tube.

[0013] According to one aspect of this disclosure, in a heat source device for a Rijke tube, the length of the second insulating member is greater than the wall thickness of the Rijke tube.

[0014] According to another aspect of this disclosure, a method of using a heat source device for a Rijke tube is provided, applied to the aforementioned heat source device for a Rijke tube, the method of using the heat source device for a Rijke tube comprising:

[0015] According to the assembly requirements of the heat source device of Rijke tube, the first insulating component is placed in the second groove;

[0016] With the first insulating member placed in the second groove, the heating element is fixed to the heating support member and placed in the first groove;

[0017] While ensuring that the first through hole on the side wall of the connector is connected to the second through hole of the first insulating member, the second insulating member is inserted sequentially along the first through hole and the second through hole until it contacts the inner side wall of the first insulating member.

[0018] With the second insulating component placed in the first through hole and the second through hole, the upstream and downstream parts of the Rijke tube are connected by the connector, and the heat source device of the Rijke tube is used to heat the inside of the Rijke tube.

[0019] According to one aspect of this disclosure, a method of using a heat source device for a Rijke tube, with a second insulating member placed in the first and second through holes, connecting the upstream and downstream portions of the Rijke tube via the connector, and heating the interior of the Rijke tube using the heat source device further includes:

[0020] When the upstream and downstream parts of the Rijke pipe are connected by the connector, the gap between the connector and the second insulating member is sealed with sealant.

[0021] The at least one technical solution adopted in this embodiment can achieve the following beneficial effects: In the heat source device for Rijke tubes, the connector is provided with a first groove for placing the heating support and a second groove for placing the first insulating component. The heating support is located in the first groove, and the first insulating component is located in the second groove. By opening the first and second grooves on the connector, the heating support and the first insulating component are fixed, effectively avoiding the problem of unstable fixing of the heating element. Based on this, the heating support is used to fix the heating element, ensuring the stability of the heating element. At the same time, the heating elements are evenly distributed on the heating support, ensuring a reasonable distribution of the heating elements and avoiding the problem of overly compact arrangement. Based on this, the first insulating component is used to isolate the energized heating element from contact with the Rijke tube. A first through-hole for placing the second insulating component is also provided on the side wall of the connector, and a second through-hole for placing the second insulating component is provided on the side wall of the first insulating component. The first and second through-holes are connected. The second insulating component is inserted sequentially along the first and second through-holes until it contacts the inner side wall of the first insulating component. The first insulating component isolates the energized heating element from the Rijke tube, preventing contact and ensuring the safety of the aforementioned heat source device for the Rijke tube. Simultaneously, the wires connected to the heating element are prevented from contacting the Rijke tube by the second insulating component, making the wiring process more convenient and safer. The aforementioned heat source device for the Rijke tube effectively solves the problems in the prior art where insufficient space for heating elements to be arranged inside the tube, overly compact arrangement, and unstable fixing lead to short circuits or contact with the tube wall.

[0037] Combustion instability results from the full coupling of unsteady heat release and sound waves in the combustion system. The well-known Rayleigh criterion states that when unsteady heat release and sound waves are in phase within the combustion system, heat energy is converted into sound energy. Within a finite time, the sound energy within the system increases rapidly. If the increase in sound energy due to thermoacoustic coupling exceeds the dissipation of sound within the system, combustion instability will occur. Conversely, when unsteady heat release and sound waves are out of phase, sound energy is converted into heat energy, and combustion instability is suppressed. The Rijke tube, used to study thermoacoustic oscillations, is typically a vertically placed, open-ended hollow tube containing a heating element. When the heating element is fixed to the lower half of the tube, the tube's resonant frequency is excited, producing a resonant sound.

[0038] In the thermoacoustic experiments of Rijke tubes, selecting a suitable heat source is a key factor in achieving oscillation phenomena and expanding the control range of heating parameters. Therefore, during the design of the heat source section, it is necessary to select a heating element of appropriate length that can withstand the required power without melting, while keeping the inner diameter of the heat source section fixed. This element must be rationally arranged and fixed within the heat source section to ensure that it neither short-circuits itself nor contacts the inner wall of the metal heat source section. However, current Rijke tube experimental research typically uses heating elements with a single heating wire or a spring-shaped heating wire. This involves winding the single heating wire or spring-shaped heating wire onto a cross-shaped or U-shaped insulating sheet, which is then fixed inside the tube for heating. However, this heating method often suffers from insufficient space within the tube, overly compact arrangement, and unstable fixation, easily leading to short circuits or contact with the tube wall. Furthermore, wiring is difficult, and the insulating sheet is prone to charring and deformation under prolonged high-temperature conditions.

[0039] To address the aforementioned issues, this exemplary embodiment provides a heat source device and method for using a Rijke tube, thereby resolving problems such as insufficient space for heating elements to be arranged inside the tube, overly compact arrangement, and unstable fixing, which can lead to short circuits or contact with the tube wall by the heating elements themselves.

[0040] A heat source device for a Rijke tube according to an embodiment of the present disclosure will now be described in detail with reference to the accompanying drawings.

[0041] Figure 1 The illustration is a cross-sectional structural diagram of a heat source device for a Rijke tube according to an embodiment of the present disclosure. Figure 2 The illustration is a schematic diagram of a heat source device for a Rijke tube according to an embodiment of this disclosure, as shown. Figures 1-2 As shown, the heat source device for the Rijke tube includes: a heating support 1, a first insulating member 2, a connector 3, a heating element, and a second insulating member 4. The connector 3 has a first groove 31 for placing the heating support 1 and a second groove 32 for placing the first insulating member 2. The heating support 1 is located in the first groove 31 and is used to fix the heating element. The heating element is evenly distributed on the heating support 1. The first insulating member 2 is located in the second groove 32 and is used to isolate the contact between the charged heating element and the Rijke tube. The side wall of the connector 3 also has a first through hole 33 for placing the second insulating member 4, and the side wall of the first insulating member 2 has a second through hole 21 for placing the second insulating member 4. The first through hole 33 and the second through hole 21 are connected. The second insulating member 4 is inserted sequentially along the first through hole 33 and the second through hole 21 until it contacts the inner side wall of the first insulating member 2.

[0042] In practical applications, such as Figure 1As shown, the connector 3 has a first groove 31 for placing the heating support 1 and a second groove 32 for placing the first insulator 2. It should be understood that the connector 3 can be a flange pipe, a threaded connecting pipe, etc.; a flange pipe is used as an example here. The heating support 1 is located in the first groove 31, and the first insulator 2 is located in the second groove 32. By opening the first groove 31 and the second groove 32 on the connector 3, the heating support 1 and the first insulator 2 are fixed, effectively avoiding the problem of unstable fixing of the heating element. Based on this, the heating support 1 is used to fix the heating element. It can be understood that the heating element can be an electric heating wire, an electric heating tape, etc., which will not be specifically described here. This disclosure uses a spring-shaped electric heating wire as an example. Compared with a single electric heating wire, the spring-shaped electric heating wire can more effectively utilize the space inside the tube, and its length can be freely adjusted, facilitating installation and wiring. The spring-shaped electric heating wire is arranged interlaced between the holes on the heating support 1, making full use of the internal space of the heat source section. The heating element is fixed to the heating support 1 to ensure its stability. Simultaneously, the heating elements are evenly distributed on the heating support 1, ensuring a reasonable distribution and avoiding overly compact arrangement. Furthermore, the first insulating member 2 isolates the energized heating element from contact with the Rijke tube. The side wall of the connector 3 has a first through hole 33 for placing the second insulating member 4, and the side wall of the first insulating member 2 has a second through hole 21 for placing the second insulating member 4. The first through hole 33 and the second through hole 21 are connected. The second insulating member 4 is inserted sequentially along the first through hole 33 and the second through hole 21 until it contacts the inner side wall of the first insulating member 2. The first insulating member 2 isolates the energized heating element from the Rijke tube, preventing contact and ensuring the safety of the aforementioned heat source device for the Rijke tube. At the same time, the wires connected to the heating element are prevented from contacting the Rijke tube by the second insulating member, making the wiring process more convenient and safer. The above-mentioned heat source device for Rijke tubes effectively solves the problems in the prior art where insufficient space for heating elements to be arranged inside the tube, overly compact arrangement, and unstable fixing lead to short circuits or contact with the tube wall by the heating elements themselves.

[0043] For example, Figure 3 The illustration is a schematic diagram of the structure of the heating support member 1 of the heat source device for Rijke tube according to an embodiment of this disclosure, as shown. Figure 3As shown, the heating support 1 is a circular heating support 1. It can be understood that embedding the circular heating support 1 within the connector ensures the stability of the heating support 1. The heating support 1 has multiple third through holes 11 and one fourth through hole 12. It should be understood that having multiple third through holes 11 ensures that the heating element can be stably inserted into each third through hole 11, guaranteeing the stability of the heating element on the heating support 1. Simultaneously, it prevents the heating elements from contacting each other during arrangement and after thermoacoustic oscillation, preventing localized melting. Each third through hole 11 is evenly distributed along the circumferential direction of the fourth through hole 12. The fourth through hole 12 is designed to ensure communication with the upstream and downstream Rijke pipes; it should be understood that the aforementioned circumferential direction is along the circumference of the connector.

[0044] For example, such as Figure 3 As shown, the outer wall of the heating support 1 is provided with a plurality of first protrusions 13. It should be understood that the heating support 1 is made of insulating and high-temperature resistant material, mainly processed from mica sheet. The connector is also provided with a plurality of third grooves, each first protrusion 13 being adapted to each third groove. It should be understood that the adaptation of the first protrusion 13 to the third groove ensures that the heating support 1 will not rotate due to the pulling of the heating element during installation, ensuring the stability of installation and fixing. At the same time, it also facilitates the disassembly and reassembly of the heating support 1 and the connector while ensuring the stability between the heating support 1 and the connector.

[0045] For example, the radial dimension of the first groove is greater than that of the second groove. In a specific application, the first groove is used to place the heating support and the second groove is used to place the first insulating member. Since the first insulating member needs to separate the heating element from the Rijke tube, it is necessary to ensure that the second insulating member cannot slide out of the connector while ensuring the use of the heat source device for the Rijke tube. Therefore, it is necessary to ensure that the radial dimension of the first groove is greater than that of the second groove.

[0046] like Figure 3 As shown, the radius of the pitch circle formed by each third through hole is smaller than the radius of the Rijke tube. It can be understood that the above-mentioned pitch circle is a circle formed by connecting the geometric centers of each third through hole 11. When the radius of the pitch circle formed by each third through hole 11 is smaller than the radius of the Rijke tube, it can be ensured that the heating element can be coiled on the heating support 1, while ensuring that the heating element will not contact the inner wall of the Rijke tube, thus ensuring that the heating element works in a safe environment.

[0047] Figure 4 This is a further illustrated schematic diagram of the structure of the first insulating member of the heat source device for a Rijke tube according to an embodiment of the present disclosure, as shown below. Figure 4As shown, it should be understood that both the first insulating component and the connecting component are hollow structures, ensuring air circulation within the pipe. Simultaneously, the second protrusion 22 on the end face of the first insulating component near the heating support effectively prevents the first insulating component from detaching after being inserted into the connecting component.

[0048] Figure 5 This is a further illustrated schematic diagram of the connection structure of a heat source device for a Rijke tube according to an embodiment of this disclosure, as shown below. Figure 5 As shown, in practical applications, both ends of the connector are metal pipes with flanges. The bolt holes and pin holes on the flanges are used to connect with the upstream and downstream Rijke pipes 5. A heating support and a first insulating component are embedded inside the connector through machining. A first through hole 33 for placing a second insulating component is also provided on the side wall of the connector. A third groove 34 for connecting each boss is provided on the connecting end face at one end.

[0049] Figure 6 This is a further illustrated schematic diagram of the structure of the second insulating component of a heat source device for a Rijke tube according to an embodiment of this disclosure, as shown below. Figure 6 As shown, the length of the second insulating component 4 is greater than the wall thickness of the Rijke tube. In practical applications, the material of the second insulating component 4 is ceramic. The second insulating component 4 is inserted sequentially along the first through hole and the second through hole until it contacts the inner wall of the first insulating component. The connecting wire of the heating element needs to be inserted into the second insulating component. The second insulating component 4 avoids the wire from contacting the Rijke tube, making the wiring process more convenient and safer.

[0050] This disclosure also provides a method of using a heat source device for Rijke tubes.

[0053] S703: While ensuring that the first through hole on the side wall of the connector is connected to the second through hole of the first insulating member, the second insulating member is inserted sequentially along the first through hole and the second through hole until it contacts the inner side wall of the first insulating member.
